To all whom t may concern: i

Be it known that I, EDWARD LAS, a .citizen of Jche United States,residing at -Chicago, in the county of Cook and State of Illinois, haveinvented certain new and u se- 1 ful Improvements in Rail-Anchors,offwhich;

the following is a specification.

My invention relates to arail anchororv anti-ci'eeper and particularlyto railv and the principal object ofthe invention is to provide noveland eii'ective means` for absorbing vibrationv between the elements ofthe device having said wedgingengagement and preventing a retrograde'movement .of one element with respect to the" other,

which movement,l if' unchecked, would necessarily impair or destroythehold ofithe flevice on the rail.

With this 4objectl in view, fthe invention consists of the novelarrangements. and devices relating orapplicable to rail anchors whichwill -be hereinafter describedv and claimed.

The invention' is illustrated, vin' 'certain preferred embodiments, inthe accompanyingv drawings wherein- Figure ll is a plan view of a railanchor constructed in accordance with my invention and shown as appliedto a rail; certain parts of the anchor being shown in section.

Fig. 2` is avertical sectional view taken onvk line 2-/2 of 1. Fig. 3 isa detail view of the elastic lelement employed for absorbing .vibrationvand preventing retrograde'- movement of/.the wedge. Fig. 4' is a sectionon line 4-4 of Fig. 3'. i Like characters of vreference .designate likeparts the g several vfigures of the drawings.7"'y f j 1 In thedrawings,A designates arail, and B one ofthe cross ties on which therail is laid.' The rail` anchor consists of two members C and D whichhave 'a wedg" i1ig re'lat'iioi'i with respect to each other andtogether-pro;

ride means for engaging the basejflange 4E- m the rail. The preciseconstruction'of the members of the i'ail anchor might be'variedconsiderably. For the purpose of illustrating the principle of myinvention I have 'adapted to bear against the ltie B.

shown the same as embodied in a rail anchor .whichin-other 'respectsisof common type.

The .member4 A is composed of a bar l0 which vextends under the baselange of the rail-fandis `formed in one end with a jaw l1 extending.around one edge of the base flange, .and on the other end with a largerjaw 12 which is provided with a flangel 13 he I nember'l) iswedge-shaped and driven inte Ja-wflQgbetween said jaw and the baseliange oftheV rail. formed with a groove 11i which embraces the 'edgevofthe base flange of the rail. The

'opposite verticali'surface15 of the wedge bearsA against the innerverticalv faecal@ of the jaw l2. The latteris formed'with a recess 17 inwhich is seated a curved or arcuate spring 18 (Figs. 3 and4,) thelends'l'), 20 of which are preferably beveledl and overlap each other.`When the wedge is driven into jaw l2 toward the tie B the spring 18 iscompressed, that is, itsdiamcter is considerably reduced. It, therefore,exerts a pressure against the wedge D which helps to maine'tainftheintimate wedging relation between the members of the-rail anchorand the base flange of the rail by absorbing Avibration, and checkingthe tendency of the wedge to lback out of the jaw. The member C of theanchor is preferably reinforced by a strengthening rib 2.

. `Imate so that any movement 'of the rail is im- Uparted to the freeend of the/anchor, thatis,

the end provide with jaw il. While means is provided, in t 'eprovision'oi;i the spring 18, for absorbing Jt/ibration and'y checking'the tendency 'of t Wedge to back away from its operative position, thisis done with the `sacrifice of brit a small amount of friction surfacebetween the two members of the anchor. Tliemembcrs of the anchor prefer-Preferably the member D is' ably engageJ rigidly with each other andWitlrthe base ange of the rail in such manner that ebnsiderable frictionis developed and so that the cramping tendency of the device on the railis fully effective. The

elastic engagement between the members is supplemental to the frictionalengagement -and 1s calculated particularly to absorb vibration whichwould otherwise have a tendency to loosen the frictional hold of onemember upon the other. The spring 18 is preferably circular in shape ornearly so, and is formed so that one end will slide over the other whenthe spring is compressed. l.

l out departure from the principles of the invention.

provided at one end The'invention, for example, is applicable to othertypes of rail anchor than the type herein obviously on anchors of thetype shown the springs might be placed in the wedge instead of the jawof the other member, although itis preferable to arrange it in the jawof the other member as there is more room and it isimpor'tant that thespring, in whichever form used,be relatively heavy.
